I'm seriously considering purchasing the above intriguing camera (I have 7 Amcrest cams presently). Hikvision sells it in 2.8mm, 4mm and 6mm lenses but I cannot find it anywhere in the desired 2.8mm lens, only a 4mm lens. Would anybody know if it's available in the 2.8mm? I'm happy to call B&H Photo (in NY) in the morning, but perhaps somebody can weigh in with their thoughts beforehand...? Thanks all.
